//| ICT EA – FVG Edition  (MQL5)  v4.3                               |
//| Architecture : BiasTF(D1) + MiddleTF(H1) + TriggerTF(M5)       |
//| State Machine: IDLE → WAIT_TOUCH → WAIT_TRIGGER → IN_TRADE      |
//|                                                                  |
//| Flow tổng thể:                                                   |
//|   1. D1 bias (UP/DOWN) đồng thuận H1 trend                     |
//|   2. H1 FVG thuận xu hướng → chờ price retrace vào FVG          |
//|   3. Giá touch H1 FVG → chờ M5 MSS xác nhận đảo chiều          |
//|   4. M5 MSS = swing break thuận chiều H1:                       |
//|      - H1 UP  → close > tH0 (phá swing high) = bull MSS        |
//|      - H1 DOWN → close < tL0 (phá swing low)  = bear MSS       |
//|      v4.3: MSS chỉ detect khi WAIT_TRIGGER, không vẽ/detect khác |
//|   5. Entry = limit tại swing level vừa bị phá (tH0 hoặc tL0)   |
//|   6. SL = swing đối diện (tL0 cho buy, tH0 cho sell)           |
//|   7. TP = Entry ± 2R                                            |
//|                                                                  |
//| Drawing: objects KHÔNG BAO GIỜ bị xóa, chỉ update              |
